【０００１】[0001]

【産業上の利用分野】[Industrial applications]

この考案は心臓外科手術，なかんずく冠状動脈バイパス手術において心臓を翻 転する用具に関するものである。 The present invention relates to a tool for inverting the heart in cardiac surgery, especially coronary artery bypass surgery.

【０００２】[0002]

【従来の技術】[Prior art]

冠状動脈バイパス手術においては，左冠状動脈回旋技および右冠状動脈後下行 枝に移植血管を吻合するために心臓の後面および下面をよく見ることができるよ うに，心臓を翻転することが必要である。従来一般的には助手が手を用いて心臓 を翻転していた。また用具として細めのテープを網状に連結した心臓翻転具が考 案され，使用されている（例えば，米国特許３，９８３，８６３号）。また金属 よってフォークのような形状の外科手術鉤が作成され用いられている（例えば， 臨床医学雑誌「胸部外科」４０巻３９ページ，南江堂，昭和６２年，東京）。 In coronary artery bypass surgery, it is necessary to invert the heart so that the posterior and inferior surfaces of the heart can be seen well to anastomoses the graft vessel into the left coronary circumflex and the right posterior descending coronary artery. is there. Conventionally, an assistant has generally used his hands to turn the heart around. As a tool, a heart inverting device, in which thin tapes are connected in a mesh, has been designed and used (for example, US Pat. No. 3,983,863). In addition, surgical hooks shaped like forks have been created and used because of metal (for example, Journal of Clinical Medicine, Chest Surgery, Vol. 40, page 39, Nankodo, 1987, Tokyo).

【０００３】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来の技術で述べたもののうち，助手が用手的に心臓を翻転する方法では（１ ）心臓が滑り落ちやすいので手術の途中で何度も翻転し直す必要がある，（２） 手指が心臓に食込んで心臓を傷害する危険がある，（３）そのために助手を雇用 する費用がかかる，等の欠点があり，何らかの方法で人手をかけずに合理的かつ 安全に心臓を翻転する用具が求められていた。 Among the methods described in the prior art, in the method in which the assistant manually turns the heart (1) Since the heart easily slips, it is necessary to turn the heart many times during the operation. (2) Finger Have the drawbacks of being able to eat into the heart and injuring the heart, and (3) thus requiring the cost of hiring an assistant, etc., to turn the heart reasonably and safely without human intervention in any way. There was a need for tools to do so.

【０００４】 米国特許３，９８３，８６３号のような網状テープを用いると確かに助手の手 を必要とせず，心臓を翻転することができるが，網状に連結されたテープが心臓 の表面を覆うために心臓表面が見にくくなり，目標とする冠状動脈を発見するこ とが困難となり，また吻合手術操作を行い難くなるなどの欠点がある。The use of a reticulated tape, such as US Pat. No. 3,983,863, does not require the help of an assistant and allows the heart to be tumbled, but the reticulatedly connected tape covers the surface of the heart. Since the surface of the heart is difficult to see because it is covered, it is difficult to find the target coronary artery, and it is difficult to perform an anastomosis operation.

【０００５】 またフォークの形状の鉤を用いるにしても助手を必要とし，また手術中に心臓 が滑り落ちる欠点を免れることができない。Further, even if a hook in the shape of a fork is used, an assistant is required and the heart slips down during surgery.

【０００６】 以上に述べた諸問題を考慮して，この考案の主目的は助手を必要とせず，安全 確実に心臓を翻転し，心臓の後面と下面の冠状動脈を容易に露出させることので きる心臓翻転具を提供することにある。In view of the above-mentioned problems, the main purpose of the present invention is that it does not require an assistant, can safely and reliably invert the heart, and easily expose the posterior and inferior coronary arteries of the heart. It is to provide a heart turning device.

【０００７】[0007]

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を目的を達成するための本考案の心臓翻転具は２本の長いテープと， それらをほぼ中央部で連結する短いテープ，および該短いテープの中央部に連結 される長いテープの約２分の１の長さのテープによって構成されるものである。 In order to achieve the above object, the heart inverting device of the present invention comprises two long tapes, a short tape connecting them at approximately the center, and a long tape connected to the center of the short tape. It is composed of a half-length tape.

【０００８】 そして短いテープは心臓に装着された時に心臓の基部を安全に支持し，かつ長 いテープを支持するために伸縮性のない丈夫な織布から成る。[0008] The short tape then comprises a durable, non-stretchable woven fabric to safely support the base of the heart when attached to the heart and to support the long tape.

【０００９】 そして短いテープの中央部に連結した長いテープの２分の１長のテープには心 臓を翻転する時に心臓の心尖部を支持固定するようにリングが設けられている。A ring that is half the length of the long tape connected to the center of the short tape is provided with a ring that supports and fixes the apex of the heart when the heart is inverted.

【００１０】 上記の４本のテープの相互の連結は縫い込みによって行ってもよく，また例え ば，熱凝固のような方法によって行ってもよい。The above-mentioned four tapes may be connected to each other by sewing, for example, by a method such as thermal solidification.

【００１１】[0011]

【実施例】【Example】

この考案の好ましい実施例を図面を参照して説明する。図１に示すようにこの 考案の心臓翻転具は長さ約８０センチメートルの２本のテープ１０，２０をその 中央部において約１０センチメートルのテープ３０で並行に連結し，さらにテー プ３０の中央部に約４０センチメートルの長さのテープ５０をテープ１０，２０ と並行になるよう連結した構造となっている。テープ５０の中央部に近い部分に はリング５５が設けられている。テープ１０，２０，および５０はいずれも幅は 約２．５ｃｍで柔らかい伸縮性のない織布からなり，テープ３０は幅は約２．５ ｃｍで柔らかい伸縮性のない織布から成る。 A preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the heart inverting device of the present invention has two tapes 10 and 20 having a length of about 80 cm, which are connected in parallel at a central portion thereof with a tape 30 having a length of about 10 cm. A tape 50 having a length of about 40 cm is connected to the tapes 10 and 20 in the central portion of the tape so as to be parallel to each other. A ring 55 is provided near the center of the tape 50. Tapes 10, 20, and 50 are all about 2.5 cm wide and made of a soft, non-stretchable woven fabric, while tape 30 is about 2.5 cm wide and made of a soft, non-stretchable woven fabric.

【００１２】 この考案の心臓翻転具を冠状動脈バイパス手術に用いる時にはテープ１０の一 端１１を肺動脈および上行大動脈の下を左から右へ通し，テープ２０の一端２１ を下大静脈の下を左から右へ通し，テープ３０が心臓の後面の房室間溝部（心臓 基部）に位置するようにする。そしてテープ１０の一端１１とテープ２０の一端 ２１は鉗子で固定しておく（図２）。When the heart diverter of the present invention is used for coronary artery bypass surgery, one end 11 of the tape 10 is passed under the pulmonary artery and the ascending aorta from left to right, and one end 21 of the tape 20 is passed under the inferior vena cava. Thread the tape from left to right so that the tape 30 is located in the interatrial groove (base of the heart) on the posterior surface of the heart. Then, one end 11 of the tape 10 and one end 21 of the tape 20 are fixed with forceps (FIG. 2).

【００１３】 そしてテープ５０のリング５５内に心臓心尖部を支持固定してテープ１０の端 １２とテープ５０の端５２を右へ牽引することにより心臓の後面の左冠状動脈回 旋枝領域を露出することができる（図３）。Then, the apex of the heart is supported and fixed in the ring 55 of the tape 50 and the end 12 of the tape 10 and the end 52 of the tape 50 are pulled to the right to expose the left coronary circumflex region of the posterior surface of the heart. It can be done (Fig. 3).

【００１４】 また同様にテープ５０のリング５５内に心臓心尖部を支持固定してテープ５０ の端５２とテープ２０の端２２を右上方へ牽引することにより心臓の下面の右冠 状動脈後下行枝領域を露出することができる。牽引したテープは鉗子で固定する （図４）。Similarly, by supporting and fixing the apex of the heart in the ring 55 of the tape 50 and pulling the end 52 of the tape 50 and the end 22 of the tape 20 to the upper right, the posterior descending of the right coronary artery on the lower surface of the heart. The branch areas can be exposed. The pulled tape is fixed with forceps (Fig. 4).

【００１５】[0015]

【考案の効果】[Effect of device]

この考案の心臓翻転具を用いることにより心臓の後面および下面を容易に露出 することができる。テープ１０と５０，およびテープ５０と２０の間隔は必要に 応じて広くとることができるので心臓表面を広く露出できる。したがって手術を 進める上で障害にならない。そして心臓は翻転された状態で安定した位置を保持 するので手術を速やかに進めることができる。さらに助手を必要としない利点が ある。 By using the heart inverting device of the present invention, the posterior and inferior surfaces of the heart can be easily exposed. The intervals between the tapes 10 and 50 and the tapes 50 and 20 can be set as wide as necessary, so that the surface of the heart can be widely exposed. Therefore, it does not hinder the operation. Then, the heart holds a stable position in the inverted state, so that the operation can be rapidly advanced. It also has the advantage of not requiring an assistant.
